Title: A Roadmap for Incorporating Physical Layer Security in 6G: Why It is Needed and How We Will Do It
Day: Tuesday, April 5, 2022
Time: 4:30 pm
Room: E-Quad, B205
Host: H. Vincent Poor
Abstract: Quality of security (QoSec) is envisioned as a flexible framework for future networks with highly diverse non-functional requirements (delays, energy conusmption, massive connectivity / scalability, computational power, etc.). In parallel, the integration of communications and sensing along with embedded artificial intelligence can provide the foundations for building autonomous and adaptive security protocols. In this talk, we will discuss how physical layer security (PLS), being naturally adaptive, fits in the QoSec framework; we will further propose a comprehensive roadmap for its incorporation in 6G, by leveraging adaptation of the transmission parameters to underlying security assumptions. In this framework, we will present smart pre-processing schemes for RF fingerprinting and secret key generation (SKG), focusing on disentangling deterministic from random components in both synthetic and real channel state information (CSI) vectors. Finally, we will present a novel approach for distributed anomaly detection in large scale Internet of Things (IoT) systems, leveraging self-monitoring of a device’s hardware (e.g., memory usage, time to Tx-Rx). Through experiments in software defined wireless sensor networks, we will discuss the potential advantages of such distributed, PHY based, anomaly detection solutions.
